Solve a^2-4a+4/a^2+ab^2-2a-2b^2

$$\frac { a ^ { 2 } - 4 a + 4 } { a ^ { 2 } + a b ^ { 2 } - 2 a - 2 b ^ { 2 } }$$

Evaluate

$$\frac{a-2}{a+b^{2}}$$

Short Solution Steps

Factor the expressions that are not already factored.

$$\frac{\left(a-2\right)^{2}}{\left(a-2\right)\left(a+b^{2}\right)}$$

Cancel out a-2 in both numerator and denominator.

$$\frac{a-2}{a+b^{2}}$$

Expand
